where \(\mathbb {P}(Z_{\rm f},N_{\rm f} | Z,N, \mathbf {q}(\xi ))\)  is the analogue of
the probability (REF ) and quantifies the probability that there is
\(Z_{\rm f}\)  protons and \(N_{\rm f}\)  neutrons in the right fragment at the
scission configuration \(\mathbf {q}\) . Here, we assume that the set of all scission
configurations can be parametrized by the coordinate \(\xi \)  forming the scission
“line” \(\mathcal {S} \equiv \lbrace  \mathbf {q}(\xi ) \rbrace _{\xi }\) . The quantity \(F(\xi )\) 
is the time-integrated flux of the collective wave packet through this scission
line. It is obtained by solving the TDGCM+GOA equation (REF ),
defining the current \(\mathbf {J}(\mathbf {q},t)\)  from the function \(g(\mathbf {q},t)\) ,
computing the instantaneous flux of that current through the scission line and,
finally, integrating it over time; we refer to [1]} and
references therein for further details.
